Bielefeld, Germany The present invention relates to garments,particularly day-shirts, provided with exchangeable collars and cuffs.

Germany, assignor to referred to by the same reference It is generallyknown that the exchangeable collars of day-shirts are fastened to theannular fastening rim at the neck-portion of the shirt either by meansof studs, or by means of buttons fastened at one part and buttonholesprovided at the other part.

off during the washing and that the studs frequently get lost. It has,therefore, already been tried to substitute for thesebutton-closing-rneans, flap like closing means.

It is further known that the sewed-on buttons usually become damaged ortorn However, the way in which the flap-like closing means have so farbeen devised has been unsatisfactory regarding the reliable-attachmentof the collar to the fastening rim and for that reasonwere the cause ofcontinuous trouble. For the detachable fastening of the culfs thedifiiculties were even more pronounced, for which reason the use ofexchangeable cuffs has in many cases already been abandoned.

Because of the quick soiling of collars and cuffs, shirts provided withexchangeable collars and cuffs are preferred by many people, althoughshirts provided with attached collars appear to be more comfortable inuse.

Hence, the object of the invention is to overcome the deficiencies ofknown constructions and to provide a dayshirt with detachable collar andcuffs which is as comfortable in use as a shirt provided with attachedcollar and cuffs.

The present invention solves the problem by providing a garment,particularly a day-shirt having at least one detachable part, an annularfastening and at each connecting place with said detachable part as oneelement, said detachable part as another element, one of said elementsto be detachable connected to one another being at least double walledand provided at a plurality of connecting points with pockets, the otherelement being provided at said connecting points with opposite fasteningtabs having parallel side edges, consisting of textile materialstifienedby chemical means, and fixed by several transverse rows ofstitches near one end for holding the tabs closely to said element in aposition for mutual cooperative self-holding action with saidcorresponding pockets, being made by sewing together portions of saiddouble-walled parts to form recesses of like shape and dimensions assaid corresponding tabs. The tabs consist preferably of an outer textilecovering and one or a plurality of stiffening strips, wrapped up in thatouter covering, whereby the stiffening strips may consist of textilestrips suited for stiffening by chemical means and heat treatment, andof strips suited for the absorption of the chemical stiffening means.

Additional features and advantages of the present invention will beunderstood from a consideration of the following detailed descriptiontaken in connection with the accompanying drawings, forming a part ofthis specification and in which two embodiments of the invention havebeen shown by way of example. However, I wish to say that the inventionis not confined to any strict 2,885,682 Patented May 12, 195974 iceconformity with the showing of the drawings, but may be changed ormodified, so long as such changes or modifications mark no materialdeparture from the salient features of the invention as expressed in theappended claim.

In the accompanying drawings, in which like parts are numerals,

Fig. 1 is a fractional view of a day-shirt provided with detachabletum-down collar and cuffs;

' Fig. 2 is a cross-section on line II-II of Fig. l; ,v Fig. 3 is afractional view of a day-shirt similar to that of Fig. 1, but having theflap-like fastening means arranged at the collar in a different way;

Fig. 4 shows in outstretched position a cuif detachably fastened to thelower end of a sleeve;

Fig. 5 is a cross-section on line V-V of Fig. 4;

Fig. 6 is a cross-section on line VI-VI of Fig. 4;

Fig. 7 shows the essential parts of a plug strip prior to being stitchedtogether;

Fig. 8 shows the plug strip of Fig. 7 stitched together and providedwith a plurality of longitudinally extending rows of stitches;

Fig. 9 shows the flap-like fastening member ready for being stitchedonto the collar and cuffs.

Referring now to the drawings in detail, the reference numeral 1designates the shirt, while 2 is the annular neck portion of the shirtto which the turn-down collar 3 is attached. Detachably fastened to thelower end of the sleeve 4 .is the cuif 5. The collar3 and-the 'cuiF-Sare provided on the outside of their inner fastening portions 13, 14with fastening flaps 6 adapted for engagement in pockets 7 formed at theinner side of the annular neck portion 2 and of the fastening portion 8of the sleeve 4. The fastening flaps 6 and appertaining pockets 7 arearranged near the ends of the collar 3 as well as the cuffs 5 and nearthe vertical center 'line of the collar and cuifs. The flaps or tabs 6have a width approximately the same as the pockets and a lengthsubstantially equal to the depth of the pockets to provide a close fit.The appertaining pockets 7 are formed at the neck portion 2 and sleeveportions -8 through circum-sewing of portions of the double-walledfastening portions 2 and 8 through the provision in the circum-sewedportions of slots provided with reinforced edges in button-hole-likefashion. All of the fastening flaps 6 and appertaining pockets 7 extendin the collar 3 of the embodiment of Fig. l transversely of thelongitudinal direction of the collar, while in the cuffs 5 of the sameembodiment the flaps and pockets extend at the ends of the culfs 5transversely of the longitudinal direction and between the two ends inlongitudinal direction of the cuifs 5. If between the ends of the cuffs5 a plurality of flaps 6 are arranged they should preferably extend inopposite directions. It is further feasible to arrange the flaps 6between the two ends of the cuffs 5 in such a way that they extend inalternately longitudinal and transverse direction, whereby then merelythe longitudinally extending flaps 6 should extend in oppositedirections with respect to each other.

Fig. 2 shows a cross-section of the collar 3 and annular neck portion 2on line 11-11 of Fig. 1.

Fig. 3 shows an embodiment in which the flaps 6 positioned near the endsof the collar extend in transverse direction, while the flaps 6 at theback of the collar 3 extend both from the vertical center line of thecollar 3 in longitudinal direction, and in opposite directions withrespect to each other, toward the ends of the collar 3.

Fig. 4 shows the end of the sleeve 4, with the cuff 5 detachablyfastened to it, in outstretched position, while Figs. 5 and 6 showcross-sections of the cuff 5 and sleeve portion 8 on lines V--V andVI-VI of Fig. 4. Here, the flaps 6 positioned near the middle of thecuff 5 extend in opposite directions toward the ends of the cuff 5whereby unintended loosening of the flaps 6 from their appertainingpockets at the sleeve portion 8 is rendered very diflicult.

.The fastening flaps :6 are formed from a 1 linen strip -9, having twicethe widthsof the .flaps, .an acetate .silk.strip 10 of .slightlysmallerwidth, and a cotton .band '11 thaving 41116 width of the ,flaps. Theseparts -are placedon top of each other (as shown in Fig. 7), thenlongitudinally folded up, then stitched together attheredges, and thenprovided witha plurality of parallel longitudinallyextendingrrows of.stitches.12,.as .shownin/Figm 8. The bandlike strip thus obtained isthen impregnated with acetone and methylic alcoholin a moist-press,whereby the artificial threads of the acetate silk become dissolved, andthen dried-and stiifenedin a hot;pr.ess. From a ,strip produced in thisway the individual flaps v6 are separated through ,punching,.cutting orthe like, with around edge at one of their ends, vwhereupon the oppositeend is fastened by two transverse rows of stitches to the collar .Zorcufi-5.
